PH was a dear friend and will be missed.
Prayers for comfort are being said for all his world wide friends.
One wonderful memory of PH is when, after a 14 + hour dive on the Titanic wreck site, he can up to the control room to be with us when our Deep Water Remote Vehicle, (TREX; Titanic Remote Explorer), dove on the Titanic wreck site for the first time, during the Discovery Channel’s Live 1998 Titanic Expedition. Tired and hungry, he stood in the control room with us during TREX’s dive, video taping, and recovery. PH’s support and efforts helped TREX to become a part of the Titanic history.
I will miss PH deeply.
